Iron concentrates obtained by the dry method are susceptible to spontaneous combustion because of the air already trapped within the concentrate during the crushing process. Due to dampness within the cargo, the sulphur can react with the oxygen to produce heat, resulting in spontaneous combustion.

Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red;

A Bessemer ore carrying 52% of iron must not have more than .052% of phosphorus and the sulphur should not exceed .04%.
